\VILLIAM W. DINGEE, OF RACINE, IVISCONSIN, ASSIGNOR TO THE .I. I. CASE THRESHING MACHINE COMPANY, OF SAME PLACE.

GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 615,144, dated November 29, 1898.

Serial No. 688,102. (No model.)

To alt whom it may concern.-

Be it known that I, WILLIAM W. DINGEE, a resident of Racine, Racine county, VVisconsin, have invented certain new and useful Improvements in Governors, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

The present invention has relation more particularly to that class of governors commonly known as centrifugal governors, in which spring-controlled weighted arms are employed.

The object of the invention is to provide improved means whereby the tension of the controlling-spring may be conveniently regulated from the outer side of the governor and without the necessity of its removal from the shaft.

The invention consists in the novel features of construction hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the claims at the end of this specification.

The present invention is shown as applied to governors especially designed for controlling the feed-carrier of a threshing-machine; but while the invention is especially adapted for such a governor it may be advantageously employed in other situations.

Figure 1 is a view in side elevation of a portion of a threshing-machine having my improved governor applied thereto. Fig. 2 is a view in side elevation of the same portion of a threshing-machine, but from the opposite side. Fig. 3 is a view in vertical section on line 3 3 of Fig. 4:. Fig. dis a view in central vertical section through Fig. 3. Fig. 5 is a view in vertical cross-section on line 5 5 of Fig. 3.

Referring to Figs. 1 and 2 of the drawings, A designates the inner end portion of the carrier-frame of a threshing-machine, adjacent which is journaled in suitable manner a shaft B, carrying at one end a gear-wheel b, with which meshes a pinion c, that is formed upon or attached to the member 0 of my improved governor. The member 0 is provided with an annular friction rim 0', adapted to fit within a belt-rim c of the member 0 of the governor, the rim 0 serving to receive a belt D, that passes over a drive-pulley E, that is carried at the end of a shaft (2, that passes from side to side of the machine, the opposite end of the shaft e carrying a pulley F, to which motion is transmitted by a belt f in the usual manner. Upon the inner face of the member 0 of the governor are formed the bosses 0 to which the arms G and G are pivotally connected by bolts 9. Each of the arms G and G is weighted, and the short end 9 of the arm G is connected by a rod H with the arm G at a short distance from its pivot-bolt g. Upon the rod II is mounted a controlling-spring K. The lower end of this spring bears against an offset 9 formed at one side of the end 9 of the arm G. The opposite end of the coil-spring H bears against a regulator M, which in the preferred form of the invention consists of a rod having an eye at one end and having its opposite end bent at an angle to the eye m and provided with a threaded portion m to receive an adj usting-nut m As shown, the outer member C of the governor is formed with an offset chamber 0 within which the body of the rod M extends, and at the bottom of the chamber C is a bearing plate or washer m through which the rod M passes and against which the adjusting-nut m will hear.

The weighted arms G and G are provided with the usual friction pads or blocks 9 adapted to bear against the inner face of the friction-rim c of the governor member 0.

From the foregoing description it will be seen that when the separator of the threshing-machine reaches the desired speed the weighted arms G and G will be thrown outward by centrifugal force until the friction pads or blocks 9 engage the rim 0 of the governor member 0, thereby causing this mem ber to revolve and through the medium of the pinion c and gear-wheel b to impart motion to the shaft B, whereby the carrier will be driven. When it is desired to adjust the spring K in order to vary the force of the spring and so insure the actuation of the carrier at the proper time and speed, the oper- IOO ator will by means of the adjusting-nut m? move the regulator or adjuster M, so as to increase or diminish the tension of the spring K, as required. lly extending the regulator or adjuster ill at one side of the governor it is manifest that the operator can without removal of parts give the desired tension to the spring K.

\Vhile I have described what I regard as the preferred form of the invention, it is obvious that the precise details of construction above set out may be varied without departure from the spirit of the invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A governor of the kind described comprising two members one of which members is provided with a friction-rim and the other of which members is provided with weighted arms and with a controlling-spring located between the members, in combination with an adjuster for said spring extending through the side wallet one of said members ata point below their rims.

2. In a governor of the kind described, the

combination with the member C having a friction-rim c and with the member 0 having a belt-rim and having the weighted arms provided with the friction pads or blocks f and with a controlling-spring, of an adjuster-rod M engaging said controlling-spring and extending through the side wall of the member C below the belt-rim and a nut whereby the adjuster M may be shifted.

In a governor of the kind described, the combination with the member 0 provided with the friction-rim c of the member C provided with the weighted arms G and G having friction-blocks g, a rod II connecting said weighted arms G and G, a coiled spring K upon said rod lI, said member 0 being provided with an offset chamber 0, and an adjuster-rod M having an eye at encircling the rod l1 and movable thereon, a plate or washer 177. through which said rod M passes and an adjustingnut m for said rod M.
